Acousto-optic research in Belgium started in 1942 by R. Mertens, at the Rijksuniversiteit, Gent and was continued by O. Leroy at the Katholieke Universiteit Leuven Campus, Kortrijk since 1972. Methods and results, used in solving light diffraction problems caused by single (progressive and standing), superposed, parallel, anti-parallel, and crossing ultrasonic beams are discussed. Optical near- and far-field are mentioned from which inverse calculations were possible.
